What is the difference between standard and undersize bearings?

Standard bearings are meant for crankshaft journals that are at their original factory size. Undersize bearings are used when a crankshaft has been machined down to correct for wear or damage, and they help restore the proper oil clearance.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit, it is always recommended to refer to the manufacturer's installation instructions or a reputable service manual for proper installation procedures and torque specifications.

What is the ACL Race Series overlay material?

The Race Series bearings feature a special overlay that is formulated for enhanced strength and durability under high-stress conditions. This material helps the bearings withstand greater loads and higher operating temperatures common in performance engines.

About this part

Product Details

ACL has been making engine bearings for decades, and this Race Series connecting rod bearing set for your Chevrolet V8 is one of their staples. These bearings are built to handle the demands of performance engines, offering a solid option for anyone rebuilding or upgrading their big block V8. They're designed to provide reliable lubrication and support for the connecting rod journals, which is crucial for engine longevity and performance, especially when you're pushing the engine harder than stock.

This particular set is for standard journal sizes, meaning it's meant to fit crankshafts that haven't been machined undersize. The Race Series bearings feature a special overlay material that's known for its strength and ability to withstand higher loads and temperatures compared to standard bearings. This makes them a popular choice for engines that see frequent hard use, track days, or are built for racing applications. When you're installing these, make sure your crankshaft journals are clean and within the specified tolerance for a smooth installation and proper oil clearance.

If you're working on a Chevrolet 396, 402, 427, or 454 cubic inch big block V8, this set is designed to fit right. It's always a good idea to double-check your engine's specific requirements and crankshaft condition before ordering, but these bearings are a well-built component for many performance builds.
